Then two other points B,C of E can be found so that the perimeter of the triangle ABC is maximized. Denote this maximum perimeter by P(A). Prove or disprove: P(A) is necessarily independent of A. --Dan _______________________________________________ math-fun mailing list math-fun@mailman.xmission.com http://mailman.xmission.com/cgi-bin/mailman/listinfo/math-fun
